Verse: 2 Corinthians 12:9
But He said to me, “My grace is sufficient for you, for my power is made perfect in weakness.” Therefore I will boast all the more gladly of my weaknesses, so that the power of Christ may rest upon me.
Regardless of what we have done God promises that His grace is sufficient. We may have weaknesses and flaws but God is all the more powerful through those weaknesses.
